10: Blood Pressure Monitoring
The first time an NBP measurement is taken, the cuff 's initial inflation pressure is 160 mmHg/21 kPa
(adult) and 120 mmHg/16 kPa (infant/child). If the measurement is successful, the next inflation
pressure is 30 mmHg/4 kPa above the systolic pressure measurement, with a minimum inflation pressure
of 120 mmHg/16 kPa. If the patient's initial systolic pressure measurement is higher than the inflation
pressure, the inflation pressure is automatically increased by 30 mmHg/4 kPa, and another measurement
is attempted. The device aborts a measurement, deflates the cuff and generates an alarm when the
inflation pressure exceeds 300 mmHg/40 kPa.
NOTES: Initial cuff inflation pressure is based on the configured patient type – adult or infant/child. If necessary,
select the correct patient type during use by changing the Patient Category selection using the Patient
Category button on the front of the HeartStart XL+.
For pediatric and adult patient populations, blood pressure measurements made with the Advantage
OEM BP Module Series are equivalent to those obtained by trained observers using the cuff/stethoscope
auscultatory method within limits prescribed by ANSI/AAMI SP10: 1992 & 2002 (mean error
difference of ±5 mmHg or less, standard deviation of 8mmHg or less).
To measure NBP:
Select the appropriately sized cuff for the patient. The cuff width should be either 40% of the limb
circumference or 2/3 of the upper arm length. The inflatable part of the cuff should be long enough
to encircle 50-80% of the limb.
NOTE: Selecting the right cuff size for the patient is important. The wrong cuff size may give false and
misleading results. If you do not have the correct cuff size, use a larger one to minimize error.
Attach the cuff to the NBP tubing, making sure that air can pass through the tubing and the tubing
is not squeezed or kinked. See
NOTE: Securely attach the cuff and tubing to prevent accidental disconnections.
Insert the NBP tubing into the NBP port as described in
Apply the blood pressure cuff to the patient's arm or leg as follows:
Ensure that the cuff is completely deflated.
Wrap the cuff around the arm, making sure that the artery marker is aligned over the brachial
artery. Ensure that:
Connecting the NBP Cuff/Tubing
The cuff is not placed on the same extremity as an SpO
The cuff is not wrapped too tightly around the limb. Excessive tightness may cause
discoloration and eventual ischemia of the extremities.
The NBP tubing from the defibrillator to the cuff is not compressed, crimped or damaged.
